Description
FIELD
[0001] The subject matter generally relates to a decorative
finishes, and more particularly, to a decoration of a metallic
appearance for article and a method for manufacturing the
decoration.
BACKGROUND
[0002] Mobile phones usually include metallic back covers and
antennas received in the metallic back covers. To prevent the
metallic back cover from interfering with signals emitted by the
antenna, a plastic portion is formed in the metallic back cover by
insert molding. The plastic portion is usually coated with a
stoving varnish with metal appearance to bring the plastic portion
and the metallic back cover to have similar colors. However, the
stoving varnish cannot form metallic textures to match the
appearance of the metallic back cover. Improvements in the art is
preferred.

DETAILED DESCRIPTION OF EMBODIMENTS
[0009] It will be appreciated that for simplicity and clarity of
illustration, where appropriate, reference numerals have been
repeated among the different figures to indicate corresponding or
analogous elements. In addition, numerous specific details are set
forth in order to provide a thorough understanding of the
embodiments described herein. However, it will be understood by
those of ordinary skill in the art that the embodiments described
herein can be practiced without these specific details. In other
instances, methods, procedures, and components have not been
described in detail so as not to obscure the related relevant
feature being described. Also, the description is not to be
considered as limiting the scope of the embodiments described
herein. The drawings are not necessarily to scale, and the
proportions of certain parts may be exaggerated to illustrate
details and features of the present disclosure better.
[0010] The disclosure is illustrated by way of example and not by
way of limitation in the figures of the accompanying drawings, in
which like references indicate similar elements. It should be noted
that references to "an" or "one" embodiment in this disclosure are
not necessarily to the same embodiment, and such references mean at
least one.
[0011] The term "comprising," when utilized, means "including, but
not necessarily limited to"; it specifically indicates open-ended
inclusion or membership in the so-described combination, group,
series, and the like.
[0012] FIG. 1 illustrates an exemplary embodiment of a decoration
of a metallic appearance 100 for article. The decoration of a
metallic appearance 100 can be applied on a back cover of an
electronic device (such as a mobile phone, not shown). The
decoration of a metallic appearance 100 includes a transparent base
layer 10, a texture layer 20, a metallic ink layer 30, and a
shading ink layer 40 stacked together.
[0013] The base layer 10 includes a first surface 11. The texture
layer 20 is formed on the first surface 111.
[0014] The texture layer 20 includes a second surface 21. The
second surface 21 faces away from the first surface 11. A number of
textures 211 can be formed on the second surface 21.
[0015] The metallic ink layer 30 is formed on the second surface 21
and fully covers the second surface 21. The metallic ink layer 30
includes a third surface 31. The third surface 31 faces away from
the second surface 21.
[0016] The shading ink layer 40 is formed on the third surface
31.
[0017] The shading ink layer 40 fully covers the third surface 31
so as to enhance a color saturation of the metallic ink layer
30.
[0018] FIG. 2 illustrates a flowchart of a method for manufacturing
a decoration of a metallic appearance 100 for article. The method
is provided by way of example, as there are a variety of ways to
carry out the method. The method described below can be carried out
using the configurations illustrated in FIGS. 1 and 3-5, for
example, and various elements of these figures are referenced in
explaining example method. Each block shown in FIG. 2 represents
one or more processes, methods, or subroutines, carried out in the
exemplary method. Furthermore, the illustrated order of blocks is
by example only and the order of the blocks can change. Additional
blocks may be added or fewer blocks may be utilized, without
departing from this disclosure. The exemplary method can begin at
block 601.
[0019] At block 601, also illustrated by FIG. 3, a transparent base
layer 10 is provided. The base layer 10 includes a first surface
11.
[0020] The base layer 10 can be made by a material selected from a
group consisting of polycarbonate, polyethylene terephthalate,
polymethylmethacrylate, and any combination thereof.
[0021] In at least one exemplary embodiment, the base layer 10 is
made by polycarbonate.
[0022] At block 602, also illustrated by FIG. 4, a texture layer 20
is formed on the first surface 111.
[0023] The texture layer 20 includes a second surface 21. The
second surface 21 faces away from the first surface 11. A number of
textures 211 can be formed on the second surface 21.
[0024] The textures 211 on the second surface 21 can be formed by
hot-pressing, ultraviolet light stamping, or out-mold
decoration.
[0025] In at least one exemplary embodiment, the texture layer 20
is made by out-mold decoration.
[0026] At block 603, also illustrated by FIG. 5, a metallic ink
layer 30 is formed on the second surface 21.
[0027] The metallic ink layer 30 includes a third surface 31. The
third surface 31 faces away from the second surface 21.
[0028] The metallic ink layer 30 fully covers the second surface
21.
[0029] The metallic ink layer is made of an UV-curable metallic
ink.
[0030] The metallic ink layer 30 can be formed by printing or
non-conductive vacuum metallization (NCVM).
[0031] In at least one exemplary embodiment, the metallic ink layer
30 is formed by NCVM.
[0032] In other exemplary embodiments, the metallic ink layer 30
can be formed by silk-screen printing using UV-curable metallic
ink.
[0033] At block 604, also illustrated by FIG. 1, a shading ink
layer 40 is formed on the third surface 31, thereby obtaining the
decorative article 100.
[0034] In at least one exemplary embodiment, the shading ink layer
40 fully covers the third surface 31, so as to improve a color
saturation of the metallic ink layer 30.
[0035] The shading ink layer 40 can be formed by printing.
[0036] In at least one exemplary embodiment, the shading ink layer
40 can be made of a material selected for a light shading
ability.
[0037] At block 604, the decoration of a metallic appearance 100 is
shaped by hot-bending or punching to obtain a desired shape.
[0038] With the above configuration, since the metallic ink layer
30 has a metallic appearance and the texture layer 20 has a number
of textures 211, the decoration of a metallic appearance 100 has a
metallic appearance. Furthermore, the shading ink layer 40 can
improve the color saturation and apparent depth of the metallic ink
layer 30.
[0039] The embodiments shown and described above are only examples.
Therefore, many such details are neither shown nor described. Even
though numerous characteristics and advantages of the present
technology have been positioned forth in the foregoing description,
together with details of the structure and function of the present
disclosure, the disclosure is illustrative only, and changes can be
made in the detail, including in matters of shape, size, and
arrangement of the parts within the principles of the present
disclosure, up to and including the full extent established by the
broad general meaning of the terms used in the claims. It will
therefore be appreciated that the embodiments described above can
be modified within the scope of the claims.
